I'm so suspicious of our own understanding of the past. I just think that your mind plays absolute tricks on you and fools you every minute of every day. And so when you're talking about the past, you're talking about something that never happened. At least it didn't happen the way you think it happened.
Overhead will eat you alive if not constantly viewed as a parasite to be exterminated. Never mind the bleating of those you employ. Hold out until mutiny is imminent before employing even a single additional member of staff. More startups are wrecked by overstaffing than by any other cause, bar failure to monitor cash flow.
